The Fourpeaked volcano, which is located in a remote part of Alaska, and which has had no known activity in the last 10,000 years, released ash, gas, and steam on 17 September, according to the Alaska Volcano Observatory (AVO). The volcano has continued to release sulfur dioxide at a rate that is similar to that measured before the January 2006 eruptions of Alaska's Augustine volcano. This indicates there is abundant, new magma within a few kilometers of the surface, said AVO research geophysicist Peter Cervelli of the U.S. Geological Survey. AVO has issued a hazard concern level of 'yellow' for the volcano (the volcano previously had no level of concern), warning that the volcano could erupt within the next days, months, or years. The Fourpeaked volcano had been unmonitored. Weather-permitting, AVO plans to soon install on the mountain a web camera, short-period seismometer, and pressure sensor to detect explosions, said Cervelli. Fourpeaked Mountain is located 320 kilometers southwest of Anchorage on the Alaska Peninsula. Additional information is available at httpc//www.avo.alaska.edu/activity/Fourpeaked.php
